WIP:

- 0.139u4: Roberto Fresca fixed clone 'Piccolo Poker 100' - Game now playable. Changed description of 'Piccolo Poker' to 'Piccolo Poker 100'. Added a workaround to get the game booting. Created inputs from the scratch. Promoted to 'working'. Added technical and game notes.

- 27th September 2010: Roberto Fresca - ANOTHER CLASSIC FROM NOVOMATIC: This is Piccolo Poker, from Admiral / Novomatic. It looks similar to American Poker II, but it's a very different game with skills things. The hardware is also a hell. All the things are scrambled. ROMs are adress bitswapped, ports, data, inputs and lights are scrambled in a strange way. Seems that they put the American Poker II hardware into a liquidisher to get this hardware. The game has also a nasty protection. The RAM has a single bit fixed at offset 0xC416 (or constantly written through a device), then check it with some boolean functions at different instances of the game. If these calculations fail, the game reset itself. I added a workaround to get the hardware happy. Here some snaps.

- 13th November 2007: Roberto Fresca - List of changes: Crystal documented via #define. CPU and sound clocks derived from #defined crystal value. Reworked TILE_GET_INFO to handle the proper tiles/color codes. Fixed interrupts (NMI). Corrected AY8910 frequency to 1.5 MHz to match the real thing. Arranged the AY8910 volume in all games to avoid clips. Corrected the screen visible area. Added NVRAM support. Reworked the memory map, mapping all the hardware I/O ports. Reworked the Inputs for all sets. Added implementation of Operator and Supervisor Keys. Fixed some timing troubles. Mapped the input buttons in the same way I mapped them in other poker games. Added partial dipswitch support with DIP locations to all sets. Removed the hack in DRIVER_INIT. Hooked write handlers for output ports. Added watchdog routines. Dumped, hooked, wired and decoded the color PROM in all sets. Colors are perfect. Modified the refresh rate to 60 fps according to hardware measurements. Cleaned up and renamed all sets, defining parent-clone relationship. Wired the lamps for all sets. Created their respective layouts. Updated flags in game drivers. Splitted the driver to driver/video. Other minor fixes. New set dumped/added: American Poker 95. New set dumped/added: American Poker 2 (bootleg, set 1). New set dumped/added: Sigma Poker. New set dumped/added: Sigma Poker 2000. Rewritten the technical notes from the scratch (still in progress). Added a PCB layout to the technical notes (still in progress). I need to finish some things and make a final cleanup before submit the driver.

- 11th November 2007: Roberto Fresca - Some time ago I made an attempt to rewrite the American Poker II driver, but I got stuck with several things. Now, thanks to an anonymous collaborator that own the board, I received a lot of technical information that encouraged me to rewrite the whole thing again... Added also a totally different set. All sets are working properly with full sound.
